Sizing notes

Measurements are stated in inches unless otherwise indicated. CHOOSING THE RIGHT SIZE: If your body measurements are midway between two sizes, select the smaller size for a tighter fit or the larger size for a looser fit. If your body measurements result in different sizes, we recommend using your chest measurement for tops and your hip measurement for pants.

Rated 3 out of 5 by from Ivory or Pink? I ordered 3 of these shirts in ivory, thinking they would be closer to white in color. As a huge fan of Icebreaker, owning several base layers and a few jackets, I was disappointed when they arrived and I opened the box to find pink shirts. Light pink, tan, skin color - however you want to call it, they certainly weren't white or "ivory." The shirts are super comfortable and again, I love Icebreaker's clothes, but what is the reasoning for such a huge color difference?

Rated 5 out of 5 by from The perfect slim t shirt I travel all over the world out of a carry on bag, and I am always looking for the perfect travel clothing. This shirt is extremely flattering with a slim fit and the merino wool means that you can wear it for several days before washing in the hotel sink. I wear Wool and Prince dress shirts on top of the Icebreaker shirt for the perfect combo of odor free comfort in any temperature under 80 F. This shirt deserves to be on your ultralight packing list.

Rated 4 out of 5 by from Great shirt - but a tight fit I love this shirt, but I normally wear medium Icebreakers shirts and find they are typically a bit on the large side, whereas this one was quite tight. I would recommend going a size up from what you normally wear.

Rated 5 out of 5 by from I wear these everyday, but I have one issue The photos don't always show whether the stiching on the side is a different color as the shirt itself. The blue shirt has white stiching! I wish the stiching was the same color, so it wouldn't stand out.

Rated 5 out of 5 by from trim fit is good Bought a medium for my 6 ft 150lb son. Fits perfect. He likes this shirt because it fits closely without being superhero tight. Counter example: he does not like the Icebreaker Tech T because it has too much material around the waist. He also prefers wool over cotton tees as long as I'm buying.

Rated 4 out of 5 by from Will this ever smell? Seriously, do these shirts ever need to be washed? I have always bought cotton shirts and wash them after 1 days use. I have been wearing this shirt on and off over 2 weeks. No hint of the usual "time to wash" smell that cotton gets. I'm sold.

Rated 5 out of 5 by from Great cold/hot weather shirt This is my 3rd icebreaker short sleeve shirt. I've worn this shirt to the bottom of the Grand Canyon and back up in 100 degree heat. This shirt was amazing in keeping me cool and dry. I highly recommend it.

Rated 5 out of 5 by from stank free for days I rotated 2 of these shirts on our through-hike of the jmt, switching between them every 3 days. they stayed stank free for the entire trip and were absurdly comfortable. this is my go-to shirt for every backpacking and backcountry skiing trip that I do.
